The problem of low.
The technical scheme that the present invention solves is that to split box of helping pull a cart be by symmetrical equipped with horizontal stroke on cell body and cell body front and rear sides outer wall
The steel integrative-structure that axle is formed, one end of cell body and bottom opening, other end closing；Split and be cased with pressure-bearing on the transverse axis for box of helping pull a cart
Roller bearing, splitting box of helping pull a cart has symmetrical two, and two blind ends for splitting box of helping pull a cart are relative, and openend outwardly, is split for two and helped pull a cart
The voussoir helped pull a cart on the outer wall of box front and rear sides is split equipped with being stuck in two between box；The structure of voussoir is the front and rear sides bottom of transverse slat
Equipped with front and rear symmetrical front panel and rear board, front panel or rear board are shape with wide top and narrow bottom, form wedge-shaped groove-like structure in portion.
The present invention has the mechanical properties such as preferable intensity, rigidity and stability, can bear test test specimen needed for pressure and
The stress deformation of test specimen will not occur, simplify the stress analysis of experiment test specimen, facilitate and test and accelerate experiment process, keep away
The interference of unnecessary factor, and its simple to operate, easy to use, escapable cost are exempted from.

Embodiment
The embodiment of the present invention is elaborated below in conjunction with accompanying drawing.
Provided by Fig. 1-Fig. 6, structure of the invention is that to split box of helping pull a cart be by right on cell body 1 and cell body front and rear sides outer wall
Claim the steel integrative-structure formed equipped with transverse axis 2, one end of cell body and bottom opening, other end closing；Split the transverse axis for box of helping pull a cart
On be cased with pressure-bearing roller bearing 3, splitting box of helping pull a cart has symmetrical two, and two blind ends for splitting box of helping pull a cart are relative, openend outwardly,
Split for two and split the voussoir helped pull a cart on the outer wall of box front and rear sides equipped with being stuck in two between box of helping pull a cart；The structure of voussoir is, transverse slat 4
Equipped with front and rear symmetrical front panel 5 and rear board 6, front panel or rear board are shape with wide top and narrow bottom, are formed for front and rear sides bottom
Wedge-shaped groove-like structure.
Described front panel 5 and rear board 6 is each perpendicular to transverse slat.
Described front panel 5 or rear board are to be docked at one by the inverted equicrural ladder plate of the rectangular slab on top and bottom
Act the slab construction wide at the top and narrow at the bottom of the integrated formed.
The described lower inner wall of front panel 5 is abutted on two front side for splitting box of helping pull a cart outer walls, rear board lower inner wall patch
Lean against on two rear side for splitting box of helping pull a cart outer walls.
It is in be pressed down against that the described bottom of front panel 5, which is placed on two pressure-bearing roller bearings split on front side of box of helping pull a cart of left and right ends,
State, it is in be pressed down against state that rear board bottom, which is placed on two pressure-bearing roller bearings split on rear side of box of helping pull a cart of left and right ends,.
Described pressure-bearing roller bearing 3 is zanjon pearl bearing.
Outer box wall of helping pull a cart of splitting where described pressure-bearing roller bearing 3 and the transverse axis to connect together has 1mm spacing.
Described voussoir is the integrative-structure of steel, and it is to accept forcing press and give pressure-bearing roller bearing pressure transmission that it, which is acted on,.
Below in conjunction with the accompanying drawings 1-6 come illustrate the present invention the course of work：The first step, first by test specimen 7（Such as Fig. 5）Top
Appropriate lubricating oil is smeared at the position of breach, secondly will be split and is helped pull a cart box at the upper notch of test specimen（See Fig. 6）；Second
Step, zanjon pearl bearing is arranged on and split on the transverse axis for box of helping pull a cart, zanjon pearl bearing has spacing, preferably 1mm with splitting box of helping pull a cart；3rd
Step, voussoir is placed between two zanjon pearl bearings on the outside of the left and right ends of voussoir bottom, forcing press is connect on voussoir and is started
Spilt test is carried out, forcing press is connect on voussoir and pressure transmission to zanjon pearl bearing and then is passed to and splits box of helping pull a cart, is finally passed
Test specimen is passed, stress is acted on to split and helped pull a cart on box by zanjon pearl bearing, and stress point can clearly be carried out by splitting the stress for box of helping pull a cart
Analysis and the pulling force of horizontal direction and the pressure of vertical direction.
The present invention can be used for cleaving with differing tilt angles, different crack locations, different-thickness size test block（Also known as
Test specimen）；The size of the stress on all directions coordinate, influence of the larger reduction frictional force to experiment can effectively be calculated.
Split box of helping pull a cart be monoblock steel plate by the mode such as wire cutting integral cutting come out and non-solder, so as to ensure that overall rigid body
Rigidity；Zanjon pearl bearing cuff avoids the interference of unnecessary factor on the transverse axis for helping pull a cart box is split, all in the present invention
Part is steel component, and deflection is smaller, can leave influence of the deformation to experiment of steel component out of consideration.The present invention may be used also
To reuse, and its simple to operate, easy to use, escapable cost, effectively reduce frictional force and negligible friction is to reality
The influence tested, increase the accuracy of experiment, structure is combined, suitable for pressure-bearing spilt test.
In the present invention, it is necessary to explanation, term " on ", " under ", "front", "rear", "left", "right", " interior ", " outer " etc.
